Does your Sinistar arcade game not work properly, or not at all?? Has the issue been narrowed down to the ROM board? Do you have to wiggle around the ribbon cable, or constantly reseat it to make it work? If so, then this is the service to get your games ROM PCB board working again as it should. After purchasing this service, we will forward you our shipping address to send your non-working ROM PCB (should look similar to the one pictured) to. You pay one price and that's it, no hidden charges or fees. Here's what is included with this service:
1) Your board will be repaired back to working status
2) The original male headers(often a cause of poor contact) will be replaced with new ones.
3) The PIA chip will be removed and installed into a new dual-wipe IC socket. This is in case you have issues in the future and this IC is suspect, you won't have to desolder it in order to replace.
4) A brand new ribbon cable will be installed
Everything remains as it was from the factory, only with newer parts for reliability.
